An improved solenoid valve

Abstract

The invention discloses an improved electromagnetic valve. The improved electromagnetic valve comprises a valve body, a valve cover, a septum sheet and a moveable iron core, wherein the valve body and the valve cover form a cavity; a plurality of openings communicated with the cavity are formed in the valve cover; the septum sheet is arranged in the cavity; the moveable iron core can move in the manner of being relative to the valve body and comprises a rocker, a jacking rod, a swing rod and a first elastomer; the rocker is rotationally arranged on the valve body to form a lever structure; the jacking rod is arranged on at least one place and is connected with the rocker; the swing rod can be rotationally arranged on the valve body and respectively pushes against the moveable iron core and the jacking rod, so that the jacking rod is driven by the moveable iron core to do liner movement, and the rocker is rotated; the first elastomer is used for resetting the rocker; the septum sheet is arranged between the openings and the jacking rod; sealing parts are arranged at the corresponding openings and can close or open the corresponding openings with the movement of the jacking rod. The phenomenon that the moveable iron core is inclined is avoided, friction between the moveable iron core and a coil is reduced, and the service life of an electromagnet is prolonged; parallel contact between the septum sheet and a valve port is guaranteed, compression is easy to perform, and the pressure resistance and the sealing property are improved.

Description

technical field [0001] The invention relates to the field of fluid control, in particular to an electromagnetic valve. Background technique [0002] As a kind of fluid control equipment, solenoid valve is widely used in various fields of modern industry. According to its working mode and principle of action, solenoid valves are divided into many types. One type of diaphragm valve controls the opening and closing of the valve port through the deformation of the diaphragm. The diaphragm valve in the prior art uses an electromagnet to push the ejector rod, and then The diaphragm is pushed by the ejector rod. In this process, because the electromagnet and the ejector rod are not coaxial, there is a certain degree of eccentricity, which leads to the phenomenon that the electromagnet is prone to skew during the ejection process, causing it to be in contact with the coil. Friction occurs between them, which not only affects performance, but also reduces service life. Contents of...
